Wiring guide GP340 radio and control

Does anyone have a wiring guide for fitting this to the RT, I haven't decided what parts to remove and what parts I could reuse and a wiring guide might help with my decision.

Not used that particular radio but usually you use a battery eliminator for power. Take off the aerial and use it remotely and use a PTT switch. On my RT. The radio was velcroed under the seat over the rear wheel. The aerial was attached on the offside at rear rack level and the PTT switch was on the Nearside bar. I picked up the power from the rear 12v socket.

Oh, and it had a wired headset.
